CARLTON Bi CHASE, OF WORCESTER, NEW YORK WHEEL.

Specification of Letters Patent.

Patented April 6, 1909.

Application filed March 19, 1908. Serial No. 422,118.

To all whom it may concern.: A

Be it known that l, CARLTON B. CHAsn, aA citizen ot the United States, residing at lVorcest'er, inthe county of Otsego and State of New York, have invented certain new and useful Improvements in Vfheels; and I do declare the following tobe a full, clear, and exact description ot' the -invent-ion, such as will enablel others skilled in the art to which it. appertains Ito mal-:e and use the same.

Thisfinvention'relates to improvements in cushion tired wheels. 'A

The object of this invention is to provide l a resilient or yieldingly mounted outer riin tor vehicle Wheels to take the place of pneuina tic tires.

A further object to provide a Wheel of 'this character. which will be simple in construction, strong, durable, efficient and Well adapted tothe purpose for which it is designed.

lith these and other objects in view, the invention consists of Certain novel features ot.construction. cinnbination and arrangement of parts as will be more fullydescribed and particularly pointed out in the appended claims.'

In the accomi'ianying drawings, lilirure 1 is a side elevation of' a wheel, partly in longitudinal section constructed in accordance with the invention; Fig; 9 is a detail cross sectional view through oneeside of the wheel. and. l-`ig.l 3 is a detail Cross sectional vien' of a modification.

Referring` more particularly to the drawings, 1 denotes the wheel having a hub 2 and spokes 3 of any suitable construction, the latter being here shown as wire spokes on the outer end oi3 which is secured an inner rim 4i Which may be formed ofwood or metal.

To the rim 4 is secured the inner ends of an annular series olf-radially disposed coils 5. Around the inner' riti l beyond thc springs 5 is arranged anvonter rim 6. The spring 5 is secured to the inner rim #l by means of a ball and'socket bearing 7, the socket S of which is embedded in a suitable cavity 9 in the inner rim 4, and is provided with an inwardly projecting bolt 10 by means of which to et-hewith the nut 11, the socket 8 is firmly .lted 'to the rim t and in the socket 9.

The spring 5 is provided at its inner end with a ball 12 vvliiolii'has limited universal movement in said socket the connection with said spring being made through the opening 13. The outer end of the spring 5 isv also provided with a ball 14 havinglimited universal movement in the socket 15,*the socket 15 resting .on the edges oi' a hole 16 in the outer rim 6.

Closely fitting around the outer rim 6 is a tire 17 of' resilient material such as rubber or wood, said tire being provided with an inner groove 18 which provides a space for the reception of the socket 15. On each side of the complete wheel rim as thus' described are the annular .ide plates 19 provided with outer shoulders 2() and inner shoulders 21. The outer rim 6 is provided with inwardly projecting flanges 22 slightly removed from the edges of' the outer rim' 6 whereby is formed a shoulder to coperate With the outer shoulder Q0 of the side plate.

The inner edge of the flange 22 provides a shoulder to cooperate With the inner shoulder 21 of thel side plate.l Passing through the portion of said side plates between the shoulders 20 and 21 and through said inwardly projecting flangesQfZ are the transverse binding bolts 23 provided With the nut 211. whereby the side plates 19 are 'l held in firm engagement with the outer rim 6.

The outer' rim 6 and the side plates are so designed and combined that the inner rim 4 has easy vertical movement between said side plates. rlhe strength and size of the springs 5 is so selected that the inner rim 4c will have a vertical play suilicient to at all,

times maintain aportion of the rim et between said side plates, but at the same time give suflicient. movement to provide a very resilient aifd easy running wheel.

In the modification shown in F ig.- 3, instead of the tire 17 being of highly resilient material, I provide an inner tire 25 of wood or the like-provideiil with the groove 1S for the reception of the socket 15. In this case, the side plates 19 are made to extend out flat without a flare as shown and the inner tire 25 is provided with an outer tire 26 of iron, said tirebeing designed to protect the inner tire 9.5 and the outer edges ofthe plates 19. `This modification is intended totion consists in dividing the socket 1.5 into two parts and holdingthe saine together by the threaded engagement or' a nut resting against the rim 6. ik flange is provided which together With the nut 27 holds the two sections oi the socket l5 in place.

in assembling` either of the forms of tires shown, all oru the various parts are assenibled first, and then the side plates 1Q are put in piace and secured vby n'ieans of the bolts 23.

In the wheel construction as herein described, -the load supported by the Wheel will be suspended by the springs above the hub of the wheel and resisted by those be'- low. The suspending and resisting power ol the springs being about equal Will maintain the hub oi the. wheel in a central posiltion. When, however, the load is such as to ilorce the lower side of the inner riin or wheel downwardly, said rim will slide between the side plates 19 which will guide said inner rim and prevent any lateral. turning or' the sanie.

Freni the foregoing description taken in connection with the accompanying drawings7 the construction and operation of the invention will be readily understood without requiring a niore extended explanation.

Various changes in the torni, proportion and the iuinor details ol construction inay ybe resorted to without departing i'roni the principle or' sacricing any of the advantages of the invention, as detined in the appended claims. f

Having thus fully described my invention, what I claim as new and desire to secure by United States Letters-Patent is:

1.- In a wheel, an outer rim and an inner rim, a plurality of' springs having their ends secured to said rims, said innerriin being provided 'with a series of recesses, sockets in said recesses, said sockets being provided with inwardly projecting'bolts by ineans of which said, .sockets are secured 'in said recesses, and balls secured to the inner end ol said springs and 'having limited universal movement in said sockets.

2. In a wheel, an outer rnn, an inner run, a plurality of springs connecting` said runs.

said inner riin being provided with a plurality otf recesses, sockets in said recesses and provided with bolts by means of which said sockets are secured to said rim, balls on the inner ends of; said sprii ,'s and having limited universal movi-:nent in said sockets, said p onteiriin beingI provided with a plurality oi' opening-s, ball and socket bearings' on the side of said extending inwardly to slidably receivetherebetween/said inner rini, a tire between the outer ed oi said plates and filling against the outer face of said onterriin, saidtire being provided with anannular groove whereby is formed a space for said ball and lsocket bearings, and bolts passing,` through said flanges and said side plates to hold said side plates in position.

ln a wheel, an outer rini and an inner riin, inwardly projectingr radial lianges iornied on said outer riin, said iiang'es being arranged near the opposite edges .of the rim whereby said edges 'forin laterally projecting annular Hannes, side plates arranged on each side of 'said rims, said plates having formed therein annular oiisets adapted to forni seats to receive the radial and lateral flanges on said outer riin, transverse bolts arranged through said plates and radial flanges on said rini, andl a. series of to connect said rinis together.

Li. A vehicle Wheel comprising a hub havini,r radially-disposed spokes, an inner riin secured to said spokes, an annular series of radially disposed springs removably secured at their inner ends to the inner riin of said wheel, an outer rini arranged around the outer ends of said springs, said rini having radially and laterally projectingannular ilanges, spring inclosing plates rigidly secured to said outer riin and loosely einbracing' said inner riin, said plates having annular offsets to receive the Hannes on said outer rim, sockets engaged with said inner and outer rims, balls` secured to the opposite ends of said springs and engaged with said sockets,y and a vtire arranged on the outer outer rini, said tire having' an annular channel on its inner side to receive the..--zeckets and balls of said outer riin.

in testii'nony whereof I have hereunto set my hand in presence of two subscribing witnesses.
